                        Improvements for LAME DirectShow filter:
                        <ul>
                            <li>Added support for the DirectShow IAMStreamConfig Interface to the LAME encoder filter output pin.
                            </li>
                            <li>Modified the DirectShow filter registration section so that the LAME Encoder filter is correctly registered in the Audio Compressors filter category. This will allow third-party encoding applications using the DirectShow System Device Enumerator Interface to correctly detect the LAME encoder when querying the Audio Compressors filter group.
                            </li>
                            <li>Modified the filter registration information so that the MP3 audio subtype is correctly reported as being supported on the encoder output pin. This will allow third-party encoding applications using the DirectShow IFilterMapper2 Interface to recognize that the LAME encoder supports MP3 output.
                            </li>
                            <li>Altered the Filter Merit Value that was being used when the filter was registered so that it is now using the standard DirectShow compressor filter merit value of MERIT_DO_NOT_USE (0x200000). Previously, the filter was being registered using a value of MERIT_SW_COMPRESSOR (0x100000), which was at a lower priority (i.e. worse priority) than MERIT_DO_NOT_USE. This prevented the LAME Encoder filter from being selected for use by some third-party encoding applications.
                            </li>
                            <li>Added code to calculate the frame length of the audio frames used for the nBlockSize element of the WAVEFORMATEX output structure. Previously this value was simply hard-coded to 1.

                    <li>Library API change: lame_decode functions are now obsolete but still present, please use hip_decode instead.
                        The reason for this change is: lame_decode functions use a single global variable within the library
                        to store decoder setup, hip_decode functions don't.
                        The encoder now uses hip_decode internally and it is now possible to use <b>clipdetect</b>
                        feature while reencoding mp3 to mp3.

                        If the output file is opened 'write-only', then LAME can't update the LAME tag.
                        In this case LAME silently overwrote the first bytes of the file and an
                        optional ID3v2 tag disappeared. Now an error message will be printed and
                        no data is written in this case.

                        The problem here was, the input files are MPEG-1 Layer2 files named as MP3s. Even if you leave out
                        the --mp3input switch LAME tried to decode the input files as Layer3 files because of the file name
                        extension and because it found some valid looking Layer3 synchronization header.
                        The fixed LAME version does not assume the file name extension is always correct and treats the files
                        depending on the first found MPEG sync word. The files in question are now correctly detected as
                        Layer2 files and transcoding does succeed.

                        The problem here was, seeking on pipes shows some different behaviour depending on C-Library
                        implementations. The workaround tries to detect it's working on a pipe and doing some
                        reading instead of seeking in that case.

                                fluctuation -- not dipping too low on some music and not increasing too
                                high unnecessarily on other music. "--alt-preset standard" provides
                                bitrates roughly within the range of 180-220kbps, often averaging close
                                to 192kbps.

                        special code level tunings (those mentioned above).

                Bug in buffering routines: in some cases, could cause
                MDCT to read past end of buffer. Rare in MPEG2,
                even more rare for MPEG1, but potentially serious!</font>

            <li>Mark Taylor: MDCT/polyphase filterbank was not
                being "primed" properly. Does not effect output unless you

                "vdbj" and "Caster" found several VBR bugs (now
                fixed):&nbsp; 1. Analog silence detection only
                checked frequencies up to 16 kHz. 2. VBR mode could
                still somehow avoid -F mode. 3. VBR mode would
                ignore noise above 16 kHz (scalefactor band 22), Now calc_noise1 will
                compute the noise in this band when in VBR mode. Not
                calculated in CBR mode since CBR algorithm has no way of
                using this information.</font>

                can have more. In MPEG1, this bug would not have effected the

                ISO psy-model/bit allocation routines removed. This allowed 
                makeframe() to be made much simpler, and most of the complicated 
                buffering is now gone. Eventually I would like the encoding
                engine to be a stand alone library.

                In response to some concerns about the quality of the encoder, I
                have rebuilt the encoder from scratch and carefully compared output
                at all stages with the output of the unmodified ISO encoder.

                Version 2.0</a> of LAME is built from the ISO source code (dist10),
                and incorporates modifications from myself and the 8hz effort. The
                output file from LAME v2.0 is <em>identical</em> to the output of
                the ISO encoder for my test file. Since I do not have heaps of time,
                I left the ISO AIFF file reader in the code, and did not incorporate
                a WAV file reader.

        <p>Working on the 8hz source code...</p>
        <ul>
            <li>
                Patched the <a href="http://www.8hz.com/">8hz</a> source

            </li>
            <li>
                45% faster than original source (on my freebsd p166).
                <ul>
                    <li>
                        m1 - sped up the mdct.c and quantize() functions [MDCTD,
                        MDCTD2, LOOPD]
                    </li>
                    <li>
                        m2 - sped up the filter_subband routine using <b>Stephane
                        Tavenard</b>'s work from musicin [FILTST]
                    </li>
                    <li>m2 - minor cleanup of window_subband [WINDST2]</li>
                    <li>
                        m2 - Cleaned up a few bits in l3psy.c. Replaced a sparse
                        matrix multiply with a hand configured unrolling [PSYD]
                    </li>
                    <li>
                        m3 - (amiga only) Added in the asm FFT for m68k (based on
                        sources from <b>Henryk Richter</b> and <b>Stephane Tavenard</b>)
                    </li>
                    <li>m4 - raw pcm support back in</li>
                    <li>
                        m5 - put in a byte-ordering switch for raw PCM reading 
                        (just in case)
                    </li>
                    <li>
                        m6 - reworked the whole fft.c file. fft now 10-15%
                        faster.
                    </li>
                    <li>
                        m7 - totally new fft routine. exploits fact that this is 
                        a real-&gt;complex fft. About twice as fast as previous 
                        fastest fft (in m6). (C fft routine is faster than the 
                        asm one on an m68k!)
                    </li>
                    <li>
                        m8

                            <li>
                                Now encodes from stdin. Use '-' as the input 
                                filename. Thanks to <b>Brad Threatt</b>
                            </li>
                            <li>
                                Worked out that the 1024point FFT only ever uses 
                                the first 6 phi values, and the first 465 energy 
                                values. Saves a bunch of calculations.
                            </li>
                            <li>
                                Added a speed-up/quality switch. Speed is 
                                increased but quality is decreased <i>slightly</i>.
                                My ears are bad enough not to be able to notice
                                the difference in quality at low settings :). 
                                Setting '-q 1' improves speed by about 10%. '-q
                                100' improves speed by about 26%. Enoding of my 
                                test track goes from 111s (at default '-q 0') 
                                to 82s (at -q 100). Thanks to <b>Jan Peman</b> 
                                for this tip.

                        m9 - fixed an error in l3psy.c. numlines[] is overwritten 
                        with incorrect data. Added a new variable numlines_s[] 
                        to fix this. Thanks again to <b>Jan Peman</b>.

                    <li>
                        m10 - Down to 106 seconds by selecting a few more compiler
                        options. Also added a pow20() function in l3loop.c to 
                        speed up (ever so slightly) calls to pow(2.0, x)

                                No speedups. Just cleaned up some bits of the code.

                                Changed K&amp;R prototyping to 'normal' format.

                                Changed some C++ style comments to normal C comments in

                                Removed the #warning from psy_data.h (it was getting
                                annoying!)

                                Removed reference in bitstream.c to malloc.h. Is there a
                                system left where malloc.h hasn't been superceded by
                                stdlib.h?

                        my PSYD hack for the spreading functions is only valid for
                        44.1 kHz - Should really put in a "if freq = 44.1 kHz"
                        switch for it. Someone might want to extend the speedup for
                        48 and 32 kHz.
